DNS Manager seems not working..

Recently I find that I cannot update the DNS records using the ISPConfig's DNS Manager.

If I add a new A record the newly added entry can be seen in the panel too, but actually it doesn't work. I checked the content of the pri.XXX.com and find that the changes are actually not made to it.

I installed the ISPConfig in a FC5. Every other things seems ok (ftp, POP , webmail, etc are alright except this DNS update).

During your last update the permission of your /var/named/chroot/var/named directory have changed so the ISPConfig manager defaults to another direcory since it does not have access right anymore and saves the new zone file in that default directory
